Alginic Acid Metabolism in Bacteria I. ENZYMATIC FORMATION OF UNSATURATED OLIGOSACCHARIDES AKD 4-DEOXY-L-ERYTHRO-5-HEXOSEULOSE URONIC ACID
Alginic acid, a high molecular weight linear polymer obtained from seaweed, is widely used as an added product to food due to its property of forming highly viscous solutions. Originally described as a polymer of n-mannuronic acid, it has now been demonstrated, by the chemical studies of Fischer and DGrfel (l), to be a ,&l-4-linked polymer of n-mannuronic and L-guluronic acid. The ratio of the ...
متن کاملIonomeric Films of Alginic Acid
Transparent, flexible films could be made by casting aqueous solutions of alginic acid, but they dissolved in water. When films were made from a solution of alginic acid and multivalent ions, they were still water soluble. However, when alginic acid films were immersed in a solution of salts with multivalent ions, they dissolved in water much more slowly, if at all. Treatment with calcium and z...
متن کاملAlginic acid metabolism in bacteria. II. The enzymatic reduction of 4-deoxy-L-erythro-5-hexoseulose uronic acid to 2-keto-3-deoxy-D-gluconic acid.
Alginase, partially purified from cell-free extracts of an Enzyme Purifiation adapted Pseudomonas, has been shown to metabolize alginic All operations were carried out in a cold room at O-3”. The acid with the resultant accumulation of the monosaccharide, preparation of the crude extract of alginic acid-grown Pseudo4-deoxy-r,-erythro-5-hexoseulose uranic acid (ketodeoxygluconalmmae has been des...
متن کاملAlduronic acid metabolism by bacteria.
In a previous study (Payne and Carlson, 1957), the metabolism of glucuronic acid and galacturonic acid by whole cells was found to proceed in a variety of enteric bacteria and plant pathogens as the result of substrate induced enzymes. Glucuronate utilization by dried cells of Serratia marcescens resulted in the production of an unidentified reducing acid which could be isolated by paper chroma...
